Abstract
Abstract Improved exploratory, pre- and post- surgical techniques are now available due to an improved endoscope which uses a housing with a window member thereon. Due to the window's angle and the air-pocket between the viewing tip of the endoscope and the window, exceptional vision is provided without the need to create artificial chambers within the body. Should the window become occluded with debris, the surgeon can easily clean the window by wiping it against a nearby organ or muscle to dislodge the debris. Since no inflating gas is used, techniques employing the endoscope create minimal trauma and are ideally suited for exploratory surgery, pre-surgical inspection of the operation site, and post-surgical inspection to assure the operation obtained the desired results.
